CVE-2025-47823 identifies a security vulnerability in Flock Safety License Plate Reader (LPR) devices running firmware versions up to 2.2. The vulnerability is classified under CWE-259, which pertains to the use of hard-coded passwords. Specifically, these LPR devices contain a hard-coded password for a system account, which cannot be changed by the user or administrator. This design flaw introduces a potential security risk because if an attacker discovers or obtains the hard-coded password, they could gain unauthorized access to the device or its management interface. However, the CVSS v3.1 base score is 2.2, indicating a low severity level. The vector string (CVSS:3.1/AV:P/AC:H/PR:N/UI:N/S:C/C:L/I:N/A:N) reveals that the attack vector requires physical proximity (AV:P), has high attack complexity (AC:H), requires no privileges (PR:N), and no user interaction (UI:N). The scope is changed (S:C), meaning the vulnerability affects resources beyond the vulnerable component itself. The impact on confidentiality is low (C:L), with no impact on integrity (I:N) or availability (A:N). No known exploits are reported in the wild, and no patches have been published yet. The vulnerability primarily risks unauthorized disclosure of information if the hard-coded password is compromised, but does not allow modification or disruption of device functions.

For European organizations, particularly those using Flock Safety LPR devices for security, traffic monitoring, or law enforcement purposes, this vulnerability could lead to unauthorized access to sensitive data collected by the devices, such as license plate information and timestamps. Although the impact on integrity and availability is negligible, unauthorized disclosure of vehicle tracking data could violate privacy regulations like the GDPR, leading to legal and reputational consequences. The requirement for physical proximity and high attack complexity reduces the likelihood of remote exploitation, but insider threats or attackers with physical access could leverage this vulnerability. This is especially relevant for organizations deploying these devices in public or semi-public areas where physical security controls may be limited. The low CVSS score suggests limited direct operational impact, but the potential privacy implications and regulatory risks are significant considerations for European entities.

Given the absence of an official patch, European organizations should implement compensating controls to mitigate this vulnerability. First, restrict physical access to the LPR devices by deploying them in secured enclosures or monitored locations to prevent unauthorized personnel from connecting to or tampering with the devices. Second, network segmentation should be enforced to isolate the LPR devices from critical internal networks, limiting lateral movement if the device is compromised. Third, monitor network traffic to and from these devices for unusual activity that could indicate unauthorized access attempts. Fourth, consider disabling or restricting remote management interfaces if not required, or enforce strong authentication mechanisms at the network perimeter. Finally, engage with the vendor (Flock Safety) to obtain firmware updates or patches as soon as they become available and plan for timely deployment. Organizations should also review and update their privacy impact assessments and data protection measures to ensure compliance with GDPR in light of this vulnerability.
